Fi EXHAUST Valvetronic Exhaust System for B9.5 Audi RS4 Avant & RS5 Coupe / Sportback

Fi EXHAUST Valvetronic Exhaust System for B9.5 Audi RS4 Avant & RS5 Coupe / Sportback

The Audi RS 4 Avant B9.5 Facelift and RS 5 Coupe/Sportback Fi EXHAUST (Frequency Intelligent Exhaust) systems are high-performance valvetronic exhaust solutions designed as direct bolt-on replacements. Made from high-grade T304 stainless steel, they deliver an exhilarating and dynamic soundtrack. Fi EXHAUST systems feature advanced valvetronic technology to control airflow, manage sound volume, and enhance overall performance and torque. Installing a full system, including a valvetronic catback and ultra-high-flow downpipe, typically results in a 5-10% horsepower increase. With valves closed, exhaust gases are routed through the muffler, ensuring a low-profile, comfortable drive. When fully open, the system produces a bold and sporty exhaust note, elevating the driving experience. Depending on the model and exhaust setup, switching between street and race modes can be done via the factory exhaust/sport button, drive modes, or the optional Fi Pro remote control upgrade. Not all options are available for every model, so consultation with a representative is advised. The unique sound and performance of the Audi RS 4 Avant B9.5 Facelift and RS 5 Coupe/Sportback Fi EXHAUST systems are achieved through specially designed muffler internals, engineered to provide the ultimate driving experience.
